A modular multiplicative inverse of an integer a is an integer x such that a ⋅ x is congruent to 1 modular some modulus m . To write it in a formal way: we want to find an integer x so that. a ⋅ x ≡ 1 mod m. We will also denote x simply with a − 1 . We should note that the modular inverse does not always exist.

WebSep 28, 2024 · Then, we can apply divide and conquer DP. The optimal "splitting point" for a fixed i increases as j increases. This lets us solve for all states more efficiently. Say we compute o p t ( i, j) for some fixed i and j . Then for any j ′ < j we know that o p t ( i, j ′) ≤ o p t ( i, j) . This means when computing o p t ( i, j ′) , we don't ...
